Series win: Proteas' shape now set in stone?

David Miller and Faf du Plessis scored sparkling centuries in a partnership of 252 runs as South Africa beat Australia by 40 runs in a one-day global in Hobart on Sunday to win the three-match series 2-1.

Certainly there was glowing praise even from sometimes parochial Australian pundits for the manner in which the tourists turned the screws before and then in the "death" phase of the home team's stiff run-chase (target 321) at Hobart on Sunday, through their inspiring, three-pronged pace arsenal of Dale Steyn, Kagiso Rabada and Lungi Ngidi.

Earlier, Australia fell the wrong side of a contentious DRS call as South Africa smacked 5-320 after being in early trouble.

"That's a tough pill to swallow", Du Plessis said of the loss.

Shaun Marsh too followed his partner after reaching the triple-digit mark.

"After 35 overs we were in a great position but they took it away at the end". South Africa have probably all but confirmed their team's desired structural makeup for the World Cup in just over six months.

They will hope their opening batsmen can get off to a better start as De Kock is key to them, but they will want to bat first if possible given the vulnerable nature of their middle to lower order but other than one potential change in the number 7 spot, they will go unchanged otherwise.

However, Pretorius swung the game back in South Africa's favour by dismissing Marsh in the next over, when the left-hander looked to whip one towards the leg side but ended up skying it to Heinrich Klaasen at wide long-on.

The ruling came at a crucial point in South Africa's innings as David Miller and captain Faf du Plessis began to bunker in at the centre of the pitch.

Du Plessis was skillful and precise in making his 125 off just 114 deliveries, a contrast to the powerful Miller, who crunched four sixes and 13 fours in his 108-ball 139.

Du Plessis was dropped on 29 and Miller escaped an lbw dismissal on 41 that was overturned on review.

Australia's chase started disastrously, losing Chris Lynn to a first-ball duck before Aaron Finch (11) and Travis Head (six) joined him.

It was down to Marsh and Stoinis to open their shoulders and look for boundaries.
